I’m having to look at a list of Bacharach’s songs for help on this, but even that doesn’t clue me in on exactly when I really became aware of him as the composer.
There are certainly a few I was used to hearing before these, but “What’s New Pussycat”, “What the World Needs Now”, “I Say a Little Prayer”, and “Do You Know the Way to San Jose” are the ones that span my high school years, and I think these cumulatively opened my eyes and ears to him.
